I wouldn't do my roles if I really hated it. I've done things I hated, but I didn't go into them thinking I would hate them. I want to have fun. I don't want to go to work and not enjoy it. So if I'm swirling around on some wires, talking to Fred Flintstone, I make it the funnest I can. I also want to be good at it. I don't want to be a crap cartoon character. I want to be proud I'm a vitamin!
I admit that when I think of the money one could make from all this, I get a little twinge. But I'm pretty happy with nerd values: Get yourself a comfortable living, then do a little something to change the world.
